gemini330 ros2 depth cloud point result_frame->dataSize() not stable

[tarikbeijing]

it is about this void :
void OBCameraNode::publishDepthPointCloud(const std::shared_ptrob::FrameSet &frame_set) {

i see that the result frame when i display it crop regularly. i have follow back the data
i see coming from camera
auto point_size = result_frame->dataSize() / sizeof(OBPoint);

dadasize 12288000
dadasize 12288000
dadasize 12288000
dadasize 11059200<<<<<----
dadasize 12288000
dadasize 12288000
dadasize 11059200<<<<<<---

later when i look the valid count
point_cloud_msg->width = valid_count;

i have also the same effect

valid_count2 : 909707
valid_count2 : 913847
valid_count2 : 911681
valid_count2 : 737903<<<<<----
valid_count2 : 909707
valid_count2 : 913847
valid_count2 : 913647

when i display the result it look like that the max opening angle regulary is not the same

it disturbing a lot the result.

in the opposite the color_depth frame dont have that problem

i used 2 different gemini 330, both has this problem, i use the last firmware and ros2 driver, lunux ubuntu 22.04
